2013-05-22iio: Correct HID light sensor name in commentsAlexandre Relange1-1/+1
The original driver was pasted from accelerometer driver, but the name of the ID was not changed. This patch fixes this comment. Signed-off-by: Alexandre Relange <alexandre@relange.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2013-01-27iio:light:tsl2563 move out of stagingJonathan Cameron3-0/+898
This driver is simple, uses the latest interfaces and contains few if any controversial elements. All of its interfaces have been in place for a long time now. Hence let's move it out of staging. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Acked-by: Peter Meerwald <pmeerw@pmeerw.net>

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging Pull staging fixes from Greg Kroah-Hartman: "Here are a number of small fixes to staging drivers for your 3.8-rc3 tree. Well, the omapdrm fixes aren't really "small" but they were waiting on a number of other drm patches to go in through the drm tree, and got delayed by my vacation over the holidays. They are totally self-contained, everyone involved have acked them, and they fix issues that people have been having with the driver. Other than that one, it's a bunch of tiny bugfixes for a number of reported issues.

2013-01-07Merge branch 'staging-linus' into staging-nextGreg Kroah-Hartman1-0/+1
This is to get the comedi fixes, and resolve the issue in comdi_test.c and comedi_fops.c that were caused by changes in both branches. It also allows the fwserial driver changes to be applied, as they required the fixes that are in staging-linus. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-01-06hid: iio: rename struct hid_sensor_iio_common to hid_sensor_commonAlexander Holler1-1/+1
The structure with common attributes for hid-sensors isn't specific to the iio-subsystem, so rename it to hid_sensor_common. Signed-off-by: Alexander Holler <holler@ahsoftware.de> Acked-by: Jiri Kosina <jkosina@suse.cz> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2013-01-06iio: merge hid-sensor-attributes.h into hid-sensor-hub.hAlexander Holler1-1/+0
The stuff in hid-sensor-attributes.h is needed by every piece which uses hid-sensor-hub and merging it into hid-sensor-hub.h makes it accessible from outside the iio subdirectory.

2013-01-03Drivers: iio: remove __dev* attributes.Greg Kroah-Hartman4-20/+19
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-12-27iio: hid-sensors: respect CONFIG_IIO_TRIGGERAlexander Holler1-0/+1
Not much to say, without that change, hid-sensor-trigger will be always compiled if HID_SENSOR_IIO_COMMON is selected which fails if CONFIG_IIO_TRIGGER is not set because CONFIG_IIO_CONSUMERS_PER_TRIGGER will not be defined.

2012-11-10staging:iio: Add support for multiple buffersJonathan Cameron2-16/+2
Route all buffer writes through the demux. Addition or removal of a buffer results in tear down and setup of all the buffers for a given device. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Tested-by: srinivas pandruvada <srinivas.pandruvada@intel.com>
2012-09-08iio: Drop timestamp parameter from buffer store_to callbackLars-Peter Clausen2-3/+2
Drop timestamp parameter from buffer store_to callback and subsequently from iio_push_to_buffer. The timestamp parameter is unused and it seems likely that it will stay unused in the future, so it should be safe to remove it.

2012-09-07staging:iio: hid-sensors Use iio_push_to_bufferJonathan Cameron1-1/+1
Consistently use iio_push_to_buffer instead of manually calling the buffers store_to callback. These crossed with Lars-Peter's patch set doing every other case. Signed-off-by: Jonathan Cameron <jic23@kernel.org> Acked-by: srinivas pandruvada <srinivas.pandruvada@intel.com>

2012-08-16iio/adjd_s311: Fix potential memory leak in adjd_s311_update_scan_mode()Alexey Khoroshilov1-3/+4
Do not leak memory by updating pointer with potentially NULL realloc return value. There is no need to preserve data in the buffer, so replace krealloc() by kfree()-kmalloc() pair.

2012-06-04iio: add LM3533 ambient-light-sensor driverJohan Hovold3-0/+959
Add sub-driver for the ambient-light-sensor interface on National Semiconductor / TI LM3533 lighting power chips. The sensor interface can be used to control the LEDs and backlights of the chip through defining five light zones and three sets of corresponding output-current values. The driver provides raw and mean adc readings along with the current light zone through sysfs. A threshold event can be generated on zone changes. The ALS-control output values can be set per zone for the three current output channels.
